Description

Calculate Spearman's rank correlation with its confidence intervals by the same method as SAS. Since fmsb-0.7.3, missing values are excluded pairwisely before calculation.

Usage

adj.bias

Logical. If TRUE, adjustment for bias is taken. Default TRUE.

conf.level

Probability for confidence intervals. Default is 0.95.
